Ten routes that prove Europe is best seen from a train window — from the Channel Tunnel to the Swiss Alps, from the Spanish high-speed network to Italy's hilltop cities. Journey times, ticket prices and exactly how to book each one.
1. London to Paris — Eurostar
The original European rail icon. The Eurostar dives under the English Channel and resurfaces in France, arriving at the centre of Paris in just over two hours. No airport queues, no baggage restrictions (within reason), and you step off the train a five-minute Metro ride from Notre-Dame.
Trains run up to 18 times daily in each direction. Book 3 months ahead for the cheapest fares — prices rise steeply in the last two weeks before departure.

Spain's AVE high-speed network is among the finest in the world, and the Madrid–Barcelona corridor is its showcase route. At up to 310 km/h, the train glides across the Castilian plateau and through the plains of Aragón, arriving in Barcelona faster than any flight when you account for airport time.
Around 20 trains run daily. Renfe's advance fares start from €15 — extraordinary value for a 630 km journey between two of Europe's most compelling cities.

The direct Eurostar from Paris to Amsterdam passes through Brussels and crosses into the Netherlands, arriving at Amsterdam's magnificent central station in just over three hours. It's one of Europe's great city-pair journeys — two of the continent's most walkable, liveable capitals connected by a single fast train.

Italy's Frecciarossa (Red Arrow) is the fastest way to connect two of the world's greatest cities. In 90 minutes you go from the Colosseum to the Duomo, from ancient Rome to Renaissance Florence. Trenitalia and Italo compete on this route, which keeps prices surprisingly low and frequency remarkably high — trains run every 30 minutes at peak times.
Tip: Book at least 2 weeks ahead and you'll often find fares under €20. On the day, the same journey can cost €50+.
5. Paris to Barcelona — TGV + AVE
The direct high-speed service between Paris and Barcelona crosses the Pyrenees without a single change of train. The French TGV hands over to the Spanish AVE at the border, and you arrive in Barcelona's city-centre station having watched the landscape shift from the Loire Valley to Catalonia.

One of Europe's great cross-border journeys. The EuroCity from Munich crosses into Austria at Kufstein, climbs through Innsbruck and the Austrian Tyrol, then tackles the Brenner Pass — the lowest Alpine crossing — before descending through the Dolomites into Italy. You arrive at Venice's waterfront station with the Grand Canal literally at your feet.

The East Coast Main Line is one of Britain's most celebrated rail journeys. LNER's Azuma trains skim the Northumberland coast, cross the Royal Border Bridge at Berwick-upon-Tweed, and pull into Edinburgh Waverley — one of Europe's most dramatically situated city stations, surrounded on three sides by the Old Town, the New Town and the castle rock.

The Amsterdam–Berlin corridor passes through the flat Netherlands, crosses into Germany at Bad Bentheim, and rolls through the Lower Saxon countryside before arriving at Berlin's glass-domed Hauptbahnhof. It's a long but rewarding journey — and with a Eurail or Interrail pass it's one of the best-value long-distance connections in northern Europe.

The Gotthard Base Tunnel — the world's longest railway tunnel at 57 km — transformed this Alpine crossing. EuroCity trains now slip through the heart of the Swiss Alps in minutes rather than hours, connecting Zurich's banking district to Milan's fashion world in just over three hours. The approach to Lugano, with Lake Lugano glittering below, is one of the great cinematic moments in European rail.

Two of Central Europe's grandest capital cities, linked by ÖBB's comfortable Railjet in under three hours. The route follows the Danube corridor, passing through the Pannonian plain and crossing into Hungary. Budapest Keleti is one of Europe's most beautiful railway stations — a fitting arrival point for a journey between two of the continent's most underrated destinations.

The biggest challenge with European train travel isn't finding the routes — it's juggling a dozen different national railways, booking platforms and timetables. Renfe in Spain, SNCF in France, Trenitalia in Italy, Deutsche Bahn in Germany, ÖBB in Austria — each has its own website, its own pricing logic and its own quirks.
The simplest approach: use Klook to compare times and prices across operators in one place, or describe your whole trip to the WoW Train AI Planner and let it build the full itinerary for you — trains, connections and hotels included.
General booking rule: Book 6–12 weeks ahead for high-speed routes (Eurostar, AVE, TGV, Frecciarossa). Night trains on the ÖBB Nightjet can sell out 3–4 months in advance for the best cabin classes.
